[mythtv-users] Qt-embedded mythtv doesnt work.

That crash sounds like the -nortti problem. I had to edit the conf file in the qt sources to make this take effect when building qt-embeded. The ./configure flags dont affect the use of this when building qt. Check that when you build qt itself the -nortti flag is not being used.
 
I have some notes at home about exactly what i changed and can forward them to you tonight if you want them.

After spending abit over 3 weeks trying to get mythtv to work with directfb/QT-embedded i've come to conclusion that support doesnt work for the Matrox g550.
 
Like i've stated in the previous posts, mplayer has no issues playing ot the tv with the -dfbmga switch,
And when running mythfrontend -qws the frontend loads up on the tv,  but clicking on 'Watch TV' causing an instant crash with no errors, which also locks up my keyboard even magic sysres dont work.
 
Mythfrontend  just says changing from WatchLiveTV to none, and it exits.
 
I've tryed to debug it following the steps posted about using GDB and setting myth to debug mode, but when i call 'run -qws' in gdb to get it to run over directfb,
GDB claims it can't find 'matroxfb' drivers, So im guessing you cant debug mythtv over directfb with gdb.
I know matroxfb drivers are loaded it shows up fine in /proc/bus/pci/devices/

Dfbinfo shows all the correct settings for my matrox g550,
also fbset -v shows the right device etc.
 

I've been emailing directfb developers and they are saying my directfb is fine and it must be a mythtv/qt-embedded problem.
 
And yes I have removed the -fno-rtti switch from the /usr/local/qt-embedded/mkspecs/default/qmake.conf
and rebuilt it with the following switch.
 
./configure -qt-gif -no-exceptions -disable-opengl -qt-imgfmt-png 
-qt-imgfmt-jpeg -qt-imgfmt-mng -thread  -qt-sql-mysql -I/usr/include/mysql/
 
builds fine.
 
 
 
Besides that im all out of ideas, 
This is the 2.6.5 kernel with fusion patch,
Latest DirectFB CVS
Latest Mythtv CVS
 
I've attached a script log of what i do when running mythtv over qt-embedded (also has dfbinfo output etc..) aswell as the mythfblog and pci.log
if anyone if anyone is interested.
